CB350 Sly... Now with 2 finger braking!!!

Re: CB350 Sly... Ton-less

I'd rather go 90+ through the curves and slow down on the straights ;D
Probably wasn't too smart to do it with 35 yr old tyres though ::) (but I have nice new ones now ;) )
 
CB350 Sly... Ton-less

Man I wish somebody sold those exhausts for 350s. I would've bought one already. I have zero friends that weld.
 
Re: CB350 Sly... Ton-less

hey, does anyone know if i can replace a rocker without taking the motor out? and also if you can change your cam timing without taking the motor out...
i have a rocker that i guess got bent in a previous life because it can't make up the distance to the valve stem and it clatters about...
also i have this weird feeling that i may not have retensioned my brand new cam chain soon enough to get the initial slack out of it and i'm wondering if i jumped a tooth...
thanks!
 
Re: CB350 Sly... Ton-less

Unfortunately, you have to pull the motor on 350 to change rocker
 
Re: CB350 Sly... Ton-less

dammit! thanks PJ! thought I might have been able to slip it out of the gap between the rocker box and the cover if I got rid of the top motor mount. Luckily it's not yet riding weather!
 
Re: CB350 Sly... Ton-less

Actually I'm not sure you do. I know for sure you don't need to pull the motor to remove the the points or tach drive housing because I've done it. Now if there is room, you can remove the top motor mounts and cambox cover and access the rockers.
 
Re: CB350 Sly... Ton-less

easy enough to check before i pull the motor... i guess i'm just being lazy! i should get on with that and my twin front discs soon before it warms up!
 
Re: CB350 Sly... Ton-less

Twin front discs?! You aren't upgrading the bike without taking more pics are you?? Say it ain't so!
 
Re: CB350 Sly... Ton-less

Latest thought is keep it a single disc and find a way to adapt a modern caliper/disc... Either way pics will follow! I want people to share my pain!
 
Re: CB350 Sly... DONE!

This picture shows you have the forks mounted backwards.

That may explain your braking issues........brakes on one side vs. front on left and rear on right.

Also the drain screws should face to the back for better drainage.

Beautiful bike, none the less.
 
Re: CB350 Sly... Ton-less

thanks!
the brake is behind the fork on purpose. i liked the look better. the brake arm being in compression rather than tension is nothing to do with my braking issue... the brake works just fine for a period correct part, i'm just finding it inadequate for my taste.

Thats kewl man......................

Yeah, I don't care much for the brakes on these CB bikes either.
 
Re: CB350 Sly... Ton-less

The brake caliper behind the fork leg was a common modification when we roadraced the CB500's / 750's back in the day and it worked just fine.
The idea is to get the weight of the caliper behind the fork leg, to give a bit quicker steering (the aft location is what you see on most bikes today). The 350's caliper mount is pretty robust and doesn't give a hoot whether its in compression or tension, just like the bigger CB's didn't.
Another thing we did on the race bikes was to get rid of the adjustment screw and spring and let the caliper float - seemed to work fine on the track but I'd need them installed to get the safety check here in Ontario.
I'm doing the same change on my 175 tracker with the CB350 forks - reversed caliper. Still a bit of fab to do since I want the speedo (we talked about this awhile ago...).
Ages ago I had a CB350 front end on a 125 road racer with a second disc bolted to the hub using longer bolts (I had spec'ed out aircraft-grade hardware). The issue of course is how to hang on the second caliper. What we designed was a mechanical antidive that had a mount for the caliper and an adjustment so you could dial in some, a little or no dive or even make the front end climb if you wanted it to under braking. Looked okay on a race bike but I think the levers and arms and pivots might look a little odd on a street bike.
Let me know what you come up with regarding a larger disc - I didn't have any luck finding a larger 4 bolt rotor, though I guess I could get a carrier machined up. The CB350 caliper mounts aren't very amenable to adaptation for a larger rotor either but I guess with enough design, welding and machining, anything is possible.
Maybe the easiest thing for you to do is adapt a CB500/550 front end; a lot of the vintage road racers back here in Ontario do this and it allows you the opportunity to run twin discs and a lot stiffer fork to boot.

Re: CB350 Sly... Ton-less

EX500 rotors will bolt onto Honda center, at least I'm told they will.
I fitted a Yamaha rotor but run out of cash to get it thinned down so it isn't finished yet
I also run calipers behind fork leg on my dual disc 550 and have done it on 360's
 
Re: CB350 Sly... Ton-less

hey, quick question for the gurus out there... my tach needle bounces around insanely at higher rpms... is that the guage itself that's pooched? I'm assuming that's the case, but is the problem ever at the cam end or with the cable?
Thanks!
 
Re: CB350 Sly... Ton-less

Have you greased the cable? It's one of the must-do's with an old bike. Pull the inner cable out and wipe it clean with a rag, maybe some P-oil. Use fingers to grease it lightly. Wipe off the top 6 inches so the grease doen't migrate into the tach mechanism.

Might as well do the speedo while you're at it.

Re: CB350 Sly... Ton-less

Thanks guys! The cable was brand new so even though I didn't specifically take note of it's lubage I'm suspecting the guage... thinking I'll get a new(er) one. I'd like to put an XL one on, even though the redline will be all wrong, because it has an angled boss for the cable to attach to which would allow the cable to get past the back of my headlight without being hard against it... anyone know if the gauges are compatible otherwise?
 
Re: CB350 Sly... Ton-less

Thanks! Nice to hear! Wheels are Excel shouldered aluminum' 18", front WM2 (1.85") rear WM3 (2.15") and the tires are Battlax front 90/90, rear 110/90... Hope that helps! Good luck with your build!
